If the burner or burner access plate gaskets
have been damaged or stretched, replace the
damaged or stretched gasket before placing the
boiler back in operation.
Filter Condition

fi lter condition gauge is present with each boiler. Inspect
the fi lter gauge regularly.
2. If the fi lter gauge marker is in the red zone, the fi lter needs
to be cleaned or replaced.
3. Clean the fi lter using compressed air. Remove the fi lter by
loosening the hose clamp with a 5/16" nutdriver. From the
inside, blow out the fi lter along each of pleats until no more
dust or debris is blown out.
4. Aft er replacing the fi lter, reset the fi lter gauge by pressing
the yellow reset butt on.
5. If the fi lter gauge marker remains in the green zone, no fi lter
cleaning or replacement is necessary.
Restart and test the boiler
